Expanding chassis for imaging systems




Title: Expanding chassis for imaging systems.
Abstract: An expanding chassis for an imaging unit is provided, the expanding chassis for use in imaging systems having a plurality of imaging units arranged in an array. The expanding chassis comprises a rigid frame for housing a light engine and related circuitry, and for mounting a screen on a front surface of the rigid frame for use with the light engine. The expanding chassis further comprises at least one expandable interface pad on at least one side of the rigid frame. The rigid frame and the expandable interface pad have a combined thermal expansion characteristic that provides an overall expansion in the expanding chassis that substantially matches the expansion of the screen. ...

USPTO Applicaton #: #20100026973
Inventors: Bryan Hemphill, Les Hirst, Dan Adema


The Patent Description & Claims data below is from USPTO Patent Application 20100026973, Expanding chassis for imaging systems.

FIELD

The present invention relates to a chassis for mounting a configurable imaging system, and more particularly to a thermally expansive chassis for mounting a plurality of imaging units for generating respective portions of a composite image.

BACKGROUND

- Top of Page


A large number of applications and potential applications exist for imaging systems such as projection displays that are used to display information. Such applications include, but are not limited to, general indoor signage (e.g. shopping malls, arcades, etc.), transportation signage (e.g. arrival/departure times, etc.), in-lobby signage for office buildings, control rooms, restaurants signage, etc.

It is known to provide large displays for signage and the like by assembling a multiplicity of small displays in an array (see, for example, WO 2006/115852 (Ostendo)). Unfortunately, in such an arrangement, adjacent displays are arranged with significant gaps so as to account for thermal expansion of each unit. Large gaps between adjacent screens have the potential to interfere with the optical transition from one display to the next, reducing overall image quality.

SUMMARY

- Top of Page


According to an aspect of an embodiment, provided is a thermally expansive interface pad that is coupled to a rigid chassis so that the combined pad and chassis thermal expansion will substantially match the screen thermal expansion.

According to a further aspect of an embodiment, provided is an expanding chassis for an imaging unit for use in imaging systems having a plurality of imaging units arranged in an array, the expanding chassis comprising:

a rigid frame for housing a light engine and related circuitry, and for mounting a screen on a front surface of said rigid frame for use with said light engine; and

at least one expandable interface pad on at least one side of said rigid frame;

said rigid frame and said expandable interface pad having a combined thermal expansion characteristic that provides an overall expansion in the expanding chassis that substantially matches the expansion of said screen.

According to a another aspect of an embodiment, in a microtile unit comprising a chassis and a screen, an improvement comprising an expanding chassis for matching the expansion noted in the screen, the expanding chassis comprising

a rigid frame for housing a light engine and related circuitry, and for mounting a screen on a front surface of said rigid frame for use with said light engine; and

at least one expandable interface pad on at least one side of said rigid frame;

said rigid frame having a first thermal expansion characteristic, said interface pad having a second thermal expansion characteristic, the combined thermal expansion characteristics providing an overall expansion in the expanding chassis that substantially matches the expansion of said screen.
